An Oral Interpreter's Approach to Selected Poetry of Langston Hughes

An Oral Interpreter's Approach to Selected Poetry of Langston Hughes

Date: December 1971
Creator: Osentowski, Mary
Description: The purpose of this study was to analyze for oral presentation a selected body of poetry by Langston Hughes. Because Hughes read his own poetry in lecture recitals throughout his career, which spanned more than four decades, it is appropriate that he be considered for such a study.

Oral Syringe Training Animals: Indiscriminable and Discriminable Punishment Contingencies

Oral Syringe Training Animals: Indiscriminable and Discriminable Punishment Contingencies

Date: May 2013
Creator: Erickson, Emilie Jane
Description: Animals are commonly trained to perform behaviors during routine husbandry procedures. However, some husbandry procedures have aversive consequences when the real procedure is performed. This commonly results in loss of the trained behavior. The present study assessed whether maintaining the antecedent environmental stimulus conditions between appetitive and aversive outcomes would prevent this effect and, conversely, whether adding a stimulus discrepancy would facilitate this effect. Three domestic rats served as participants in a multiple baseline across participants design with multi-element components. All three rats stopped performing a trained behavior when a discrepant stimulus reliably predicted an aversive outcome. In addition, all three rats continued to perform the same behavior when antecedent environmental stimulus conditions were consistent between aversive and appetitive outcomes. Results are discussed in terms of practical implications for behavior change agents and conceptual implications for learning theory.

Orchestral Etudes: Repertoire-Specific Exercises for Double Bass

Orchestral Etudes: Repertoire-Specific Exercises for Double Bass

Date: August 2011
Creator: Unzicker, Jack Andrew
Description: In this project, frequently required double bass orchestral audition excerpts as well as their individual technical difficulties are identified. A survey of professional double bass players and teachers currently and formerly employed by major orchestras, universities, and conservatories have participated to validate the importance of four of the most frequently required orchestral excerpts: Ludwig van Beethoven’s Symphony No. 9, Mvt. 4, and Symphony No. 5, Mvt. 3; Richard Strauss’ Ein Heldenleben; and Wolfgang Amadeus Mozart’s Symphony No. 40, Mvt. 1. The survey respondents identified the primary and secondary technical concerns of each of the four excerpts. I have created technical studies, or etudes, that specifically address these difficulties and help fill a literary gap within the existing pedagogical resources for the double bass.

Order effects of variability-contingent and variability-independent point delivery: Effects on operant variability and target sequence acquisition.

Order effects of variability-contingent and variability-independent point delivery: Effects on operant variability and target sequence acquisition.

Date: May 2004
Creator: Lee, Coral Em
Description: Previous research has shown that variability is a reinforceable dimension of operant behavior. Additionally, it has been demonstrated that learning is facilitated when variability in responding is high. In this research, variability was observed within an operant composed of any sequence of six left and right key presses. Variability was either a requirement for point delivery (VAR conditions) or points were delivered independent of variability (ANY conditions). Two groups of college undergraduates experienced different orders of conditions. One group began the experiment under VAR conditions, and the variability requirement was later removed. The other group began the experiment under ANY conditions, and the variability requirement was later added. A concurrently reinforced target sequence (i.e., an always-reinforced sequence of left and right key presses) was introduced to both groups after these orders of conditions had been experienced. A variety of outcomes resulted. Subjects learned the target sequence when variability was both high and low with non-target points concurrently available. Other subjects learned the target sequence after all non-target point deliveries had been suspended. One subject failed to acquire the target sequence at all. These results were compared to previous findings and possible explanations for the discrepancies were suggested.

Organic carbon dynamics of the Neches River and its floodplain.

Organic carbon dynamics of the Neches River and its floodplain.

Date: December 2007
Creator: Stamatis, Allison Davis
Description: A large river system typically derives the majority of its biomass from production within the floodplain. The Neches River in the Big Thicket National Preserve is a large blackwater river that has an extensive forested floodplain. Organic carbon was analyzed within the floodplain waters and the river (upstream and downstream of the floodplain) to determine the amount of organic carbon from the floodplain that is contributing to the nutrient dynamics in the river. Dissolved organic carbon was significantly higher at downstream river locations during high discharge. Higher organic carbon levels in the floodplain contributed to increases in organic carbon within the Neches River downstream of the floodplain when Neches River discharges exceeded 10,000 cfs. Hurricane Rita passed through the Big Thicket National Preserve in September 2005. Dissolved organic carbon concentrations recorded after Hurricane Rita in the Neches River downstream of the floodplain were significantly higher than upstream of the floodplain. Dissolved organic carbon was twice as high after the hurricane than levels prior to the hurricane, with floodplain concentrations exceeding 50 ppm C. The increase in organic carbon was likely due to nutrients leached from leaves, which were swept from the floodplain trees prior to normal abscission in the fall. ...

The Organic-Progressive Principle in the Political Thought and Internationalism of Woodrow Wilson

The Organic-Progressive Principle in the Political Thought and Internationalism of Woodrow Wilson

Date: December 2011
Creator: Flanagan, John Patrick
Description: This is an investigation of the intellectual roots of the political thought and internationalism of Woodrow Wilson, the twenty-eightieth president of the United States. Exposed to the influence of Darwin, Wilson believed that politics had to be redefined as an evolutionary process. the older mechanical understanding of politics was to be replaced with an organic understanding of political development. This allowed Wilson to synthesize a concept of politics that included elements from the Christian tradition; the English Historical School, particularly Edmund Burke; and German idealism, including G.W.F. Hegel. However, because he placed a heavy emphasis on Burke and Hegel, Wilson moved away from a natural rights based theory of politics and more towards a politics based on relativism and a transhistorical notion of rights. Wilson had important theoretical reserves about Hegel, as a result, Wilson modified Hegel’s philosophy. This modification took the form of Wilson’s organic-progressive principle. This would greatly affect Wilson’s ideas about how nations formed, developed, and related to one another. This study focuses on Wilson’s concept of spirit, his theory of history, and his idea of political leadership. the organic-progressive principle is key to understanding Wilson’s attempts to reform on both the domestic and international levels.
